The Symmetry Plane is specified by a Frame3d where the XY axes define the plane and the Z axis is the plane normal. So references to "Positive" side below are relative to that Z axis/plane
class FMeshPlanarSymmetry
bool
bCanIgnoreDegenerateSymmetries
If true, symmetry-finding can return false if it detects a symmetry where all points are on the symmetry plane, rather than attempt to fit a symmetry plane in that case.
